WATCH: How Baytown businesses handled ExxonMobil plant fire
The material is easily ignited by heat, sparks or flames and will form explosive mixtures with air.
Any cylinders exposed to the fire may vent and release flammable gas through pressure relief devices.
When it comes to the health impacts of the gas, vapors may cause dizziness or asphyxiation without warning.
Contact with gas or liquefied gas can also cause burns, severe injury and/or frostbite.
ExxonMobil released the following initial statement about the fire:
A fire has occurred at the Baytown Olefins Plant. Our fire teams are working to extinguish the fire. We are conducting personnel accounting. Our first priority remains the safety of people, including our employees, contractors and the surrounding community. As a precaution, our Industrial Hygiene staff is conducting air quality monitoring at the site and fence line. We are cooperating with regulatory agencies. We deeply regret any disruption or inconvenience that this incident may have caused the community.
WHAT TO DO DURING A SHELTER-IN-PLACE
Harris County Sheriff Ed Gonzalez tweeted that his department is monitoring the situation and is ready to respond if needed.
The Texas Commission on Environmental Quality is headed to the scene.
ExxonMobil's website states that the Baytown Olefins plant began operations in 1979 and is one of the largest ethylene plants in the world.
ExxonMobil recently completed the construction of a multi-billion dollar ethane cracker at the Olefins Plant. ExxonMobil says the cracker has a capacity of 1.5 million tons per year and provides ethylene feedstock to two new high-performance polyethylene lines at the Mont Belvieu Plastics Plant, which was built in 1982. The projects were part of ExxonMobil's 10-year, $20 billion Growing the Gulf expansion program.
This is the second time within a few months that a fire has broken out at an ExxonMobil plant. That previous incident occurred in March.
